CART stands for Communication Access Realtime Translation. CART is a service in which a CART provider listens to speech and instantaneously translates all the speech to text, as well as providing audible cues such as laughter, applause, alarm bells, etc., so that the hard-of-hearing client is able to understand exactly what is happening in the room. The realtime text may be displayed as a full screen of text on a laptop, notebook, or iPad, or as large text on a screen at the front of the room, or the text may be transmitted to a website so that it may be viewed on any of the above as well as a moble device (smartphone).
